mtd: spi-nor-core: Do not set data direction when there is no data

Even when spi_nor_write_reg() has no data to write, like when executing
a write enable operation, it sets the data direction to
SPI_MEM_DATA_OUT. This trips up spi_mem_check_buswidth() because it
expects a data phase when there is none. Make sure the data direction is
set to SPI_MEM_NO_DATA when there is no data to write.
